A security researcher said that he has developed malware for Microsoft's forthcoming Windows 8 operating system that is able to load during boot-up when it's run on older PCs.
Peter Kleissner said Stoned Lite – as the latest version of his bootkit is called – doesn't bypass defenses that will be available to people using Windows 8 on newer machines.
Specifically, he said in a series of Twitter messages, it doesn't work against PCs using UEFI (Unified Extensible Firmware Interface), which is being held out as a replacement to Bios ROM firmware. Stoned Lite also doesn't attack a low-level security feature known as Secured Boot, which scans boot drives for invalid signatures prior to starting up.
A previous boot kit – which Kleissner called Stoned – works on Windows 2000 through Windows 7 and is able to load before Windows starts by attaching itself to the master boot record of a targeted PC's hard drive. Stoned Lite is able to do the same thing for Windows Server 2008 and Windows 8, the Vienna-based developer and researcher said. It works by bypassing the Windows User Account Control, and with a footprint of just 14KB, it can easily be unleashed from a USB or CD drive.
Kleissner said he plans to release further details at next week's Malcon conference in India.
Microsoft's announcement in September that it planned to use UEFI was almost immediately met with suspicion from open-source boosters, who claimed the feature could make it impossible to run systems such as Linux and FreeBSD on computers that had adopted the alternative firmware. Microsoft has denied such claims, but many critics still aren't convinced.
Whatever the merits of that argument, the inability of Stoned Lite to penetrate UEFI and Secured Boot are the strongest endorsements to date that the features work as advertised. At least for now. ®
This article was updated to clarify UEFI and Secured Boot.

Windows XP Still Tops Desktop Operating System Market Share !!
Windows XP usage dips but but still won't give up its crown as the most used operating system. It is 10 years since Microsoft released the Windows XP operating system, and in those years Microsoft has tried to tempt users away with not just one, but two major OS releases, neither of which seemed to be able to pull entrenched, and mostly business, users away from XP.
Tell us in comments which Destkop OS you use ?

Windows 8 to be more memory efficient than Windows 7
Another week and there’s more news on Windows 8 being put up on Microsoft’s Building Windows 8 blog. This latest bit of information says that Windows 8 will use less memory than Windows 7. A screenshot shows Windows 8 being set to consume just 281 MB as compared to Windows 7’s 404 MB in similar conditions - that’s more than a 40 percent drop in memory consumption on an idle mode. The demonstration system was running both operating systems with just 1GB of memory. These are still early days, so it’s hard to say exactly how efficient Windows 8 may be, and under what conditions. Performance will also vary based on what kind of system you use and what drivers might be loaded on it.
More than just a new face
Microsoft has tried to cut down redundant information stored in the memory. Another change being made is to the way services are initialized when Windows boots. Services will be started when needed, left on an idle mode for a while after the task is completed and then terminate. Some non-critical services will not be loaded during startup. While using the Metro interface, only essential components of the OS will be loaded. There will also be better prioritization of resources for applications, which means less important programs will not idle in the memory for too long.

A Journey of Microsoft: Windows NT to Windows 8 [PICS] !!
Microsoft introduced an operating environment named Windows on November 20, 1985. Microsoft Windows came to dominate the world's personal computer market. Windows have approx 90% of the market share of the client operating systems for usage on the Internet.
Windows NT
When Windows NT releases on July 27, 1993. Windows NT 3.1 is a 32-bit operating system, which makes it a strategic business platform that supports high-end engineering and scientific programs.Windows 95
On August 24, 1995, Microsoft releases Windows 95, selling a record-setting 7 million copies in the first 5 weeks. Win 95 features the first appearance of the Start menu, taskbar, and minimize, maximize, and close buttons on each window. To run Win 95, you need a PC with at least 4 MB of RAM.Windows 98
Released on June 25, 1998, Windows 98 is the first version of Windows designed specifically for consumers. Windows 98 is the last version based on MS‑DOS.Windows 2000
Windows 2000 was released to manufacturing on 15th December 1999 and launched to retail on 17 February 2000. Win 2000 adds major improvements in reliability, ease of use, Internet compatibility, and support for mobile computing.Windows XP
On October 25, 2001, Windows XP is released with a redesigned look and feel that's centered on usability. Win XP is compiled from 45 million lines of code.Windows VISTA
Windows Vista is released in 2006 with the strongest security system yet. More than 1.5 million devices are compatible with Windows Vista at launch.Windows 7 is released in October 2009. By the fall of 2010, Windows 7 is selling seven copies a second—the fastest-selling operating system in history.
Windows 8
Microsoft has not yet announced a ship date for Windows 8, although some major media outlets speculate it might be available in late 2012. Reviewers consider that there is little reason to choose Win 8 over Win 7, unless using a touch-screen device.Saturday, 27 August 2011
Microsoft Said : Windows 8 Will be As Revolutionary As Windows 95
Microsoft Corp's Windows 95 truly reinvented the PC experience and revolutionized the PC industry back sixteen years ago in 1995. This week Microsoft opened up Windows 8 development blog and said that its next-generation Windows 8, which will be available for public testing in the coming months, will be as revolutionary as the legendary Windows 95.
"So much has changed since Windows 95 - the last time Windows was significantly overhauled - when the 'desktop' metaphor was established. Today more than two out of three PCs are mobile (laptops, netbooks, notebooks, tablets, slates, convertibles, etc.). Nearly every PC is capable of wireless connectivity. Screen sizes range from under 10" to wall-sized screens and multiple HD screens. Storage has jumped from megabytes to terabytes and has moved up to the cloud," said Steven Sinofsky, the president of Windows and Windows Live division at Microsoft.
Although Microsoft continues to remain mum about the release date of Windows 8, many believe that the next-generation Windows will be launched in 2012. In its new blog, the world's largest designer of software plans to share how it focuses on performance, reliability, compatibility, security, and quality of Windows 8 and plans to continue the dialog around performance and fundamental engineering of Windows with its customers and end-users.
Microsoft previewed its Windows 8 in June and started by showing user experience and interface on a range of mobile devices. The graphics user interface (GUI) is one of the most important elements of operating systems as end-users interact with it every day. But Microsoft stresses that the new GUI along with compatibility with ARM-based system-on-chips are not the only innovations when it comes to Windows 8. The software giant claims it has engineered changes across the full range of Windows capabilities.

"We know people who care a lot about networking want to know our plans there. We know people who are invested heavily in storage want to know what is new in that area. Many want to know about performance and fundamentals. We know developers, IT pros, and gamers all want to know what's new for them. There is so much packed into Windows 8 and there are so many unique and important lenses through which to view Windows 8, and so we want to be sure to take the time to cover as many of these topics as possible, to build up a shared understanding of why we’ve taken Windows where we have. So in the next weeks we will just start talking specifics of features, since there is no obvious place to start given the varying perspectives. From fundamentals, to user interface, to hardware support, and more, if something is important to you, we promise we'll get to it in some form or another," said Mr. Sinofsky.

Happy Birthday Windows XP (Microsoft is Celebrating the 10th Anniversary of XP)
Many Many happy returns of the day, wish you a very very happy birthday dear Windows XP. Microsoft shipped the first copies of Windows XP to PC manufacturers 10 years ago today. Short for “eXPerience”, the successor to Windows 2000 and Windows Me eventually became the most popular operating system of all time. Windows XP is the first consumer-oriented OS built on the Windows NT kernel. The OS had a long run despite a rocky launch and has sustained two subsequent releases, the dreaded Windows Vista and the much-improved Windows 7.
Just one month before the official retail release of XP, a group by the name of devils0wn released a volume license key used to bypass product activation. This allowed potentially millions of users to install the operating system without paying for it. Furthermore, the events of September 11, 2001 put a damper on Microsoft’s retail launch plans and the company decided to scale back worldwide launch parties accordingly.
OEM and retail sales of XP ceased in June 2008, although Microsoft continued to offer the OS to system builders through early 2009. Support will be offered for systems running Service Pack 3 through April 8, 2014. As of last month, Windows XP finally fell below the 50 percent mark among all Windows Internet users. The slow decline is partially due to the success of Windows 7, which now accounts for nearly 30 percent of the market.
Microsoft has been urging customers to upgrade from XP since Vista arrived in 2006 and again when 7 debuted in 2009. According to free antivirus software provider Avast, XP is home to 74 percent of their customers' rookit infections.

Windows 8:Detailed
Microsoft debuted Windows 8 at the D9 conference, as well as at a separate preview event atComputex 2011. A lot of details poured in, and we’ve sifted through the lot, and laid the tastiest nuggets about the platform-spanning operating system out for you below. Also check out the must see preview video, further ahead:
- The next version of Windows is being called Windows 8 internally at Microsoft, and will work on both x86 and ARM platforms.
- There won’t be multiple versions of Windows, just one version of Windows running on a variety of hardware platforms and devices/form factors. It therefore has to be light, efficient and modular.
- It is designed to be used either by touch, keyboard and mouse, or all three.
- The same applications and programs will work on both x86 and ARM-based devices, completely cross-platform, as they will be based on the Windows 8 application development platform.
- Apps and programs will be designed for work in one of two environments.
- a) The traditional Windows 7 UI we are all comfortable with.
- b) A tile-based Metro UI-styled Start screen with Live Tile apps and feeds, based on HTML5, JavaScript and CSS.
- Apps in this environment will be ‘chrome-less’, expanding to full screen.
- Has a similar taskbar to regular Windows 7 UI, auto-hidden in a corner
- Apps can be switched simply by swiping.
- All files on the entire system can be accessed from either UI. All programs can be launched in either UI.
- Both application environments have been optimized for both touch as well as non-touch input configurations.
- Legacy apps meant for previous versions of Windows will be supported
- User can switch between environments instantly, as well as have a Aero Snap enabled split-screen interface, with Win 7 UI and Metro UI side by side, and the ability to snap and resize all types of apps to best utilise the multi-tasking ability
- The 'full screen experience' is designed for 16:9 widescreens, with a recommended minimum 1366x768 resolution for the best Windows 8 experience. 1024 x 768 is the absolute minimum for both Tile UI nd Win 7 UI to run, while 1024 x 600 is the minimum for just Win 7 UI.
- New Internet Explorer 10, again optimized for touch with a new ribbon interface.
- Built in Windows App Store
- ‘Always on, always connected’ mode for ARM devices, for instant wake-up from sleep, and apps that are constantly connected to the web.
- Great battery life for portable devices.
- UEFI-style BIOS for ultra-fast boot times.
- Support for a whole range of new sensors (especially relevant for tablets).
- Will also feature OEM Activation 3.0, helping both end users and hardware partners.
- Will come out in 2012.
That’s all for now folks, check out the must see video below, to enjoy the eye-candy that is Windows 8:

Windows Password Length:Change your way
By default Windows accepts both short and long passwords as the Windows login password.
Some users use extremely short passwords, which can easily be brute forced. So in order to set the minimum number
of characters or the minimum length of the password, simply follow the following registry trick-:
1. Launch the Windows Registry Editor i.e. c:\windows\regedit.exe
2. Scroll down to the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Network
3. Click on Edit > New DWORD Value.
4. Name this new DWORD value as MinPwdLen and in the data field, enter the minimum number of characters
the password has to be of. One thing to note here is that this value is in Hexadecimal.
5. Now, Press F5 and your system just became a tiny bit securer but certainly not unhackable.

All about Microsoft Windows 8.
Only Microsoft knows how the abutting adaptation of its Windows operating arrangement will attending and what it will be called, but big changes could be advanced for the OS that assemblage accredit to as "Windows 8."
At this year's Consumer Electronics Appearance in Las Vegas, Microsoft appear that Windows 8 will abutment system-on-a-chip architectures appliance ARM processors. Unlike the x86 architectonics that today's Windows laptops and desktops assignment with, ARM-based chips tend to run such low-power accessories as tablets and smartphones.
In his CES keynote speech, Microsoft CEO Steve Ballmer said, "This advertisement is absolutely all about enabling a fresh chic of hardware, and fresh silicon ally for Windows, to accompany the widest accessible ambit of anatomy factors to the market."
In added words, Windows won't be aloof for laptops and desktops anymore.
Actual Facts
Microsoft's ARM advertisement represents the firm's abandoned acutely appear absolute detail about Windows 8. Consistent with it, the aggregation alleged Nvidia, Qualcomm, and Texas Instruments as silicon partners, so Windows accessories congenital aloft their three low-power platforms are likely.
At an architectural acme in London aftermost year, Microsoft encouraged the abstraction of virtualizing Windows added heavily, possibly autumn apps, data, Windows settings, and genitalia of the OS itself in the cloud.
Rumors
No rumor about Windows 8 is added absolute than a alternation of leaked slides that allegedly accommodate a adapt for Microsoft's abutting OS. The slides abandoned don't announce final appearance of Windows 8, but they do appearance area Microsoft is headed, abnormally back added letters accept corroborated them.
One slide, for example, talks about an OS that follows users wherever they go; instead of actuality tethered to hardware, users may roam amid desktops, laptops, and tablets in whatever way is best convenient.
Another accelerate speaks of a displace button that preserves apps and settings while wiping out bacilli and added hindrances. Some industry watchers advance that autumn apps and abstracts in the billow could accomplish this affection possible.
As for Microsoft's ambition of "instant on" computing, blogger Manan Kakkar spotted a Microsoft apparent for appliance a hypervisor-another virtualization method-to breach the operating arrangement into a general-purpose OS and a cardinal of appliancelike applications, such as for TVs and tablets. Those uses, Kakkar says, could about-face on instantly alike if the amount OS took 30 abnormal to alpha up.
How will Microsoft accomplish these failing versions of its operating system? A rumor broadcast by Paul Thurrott posits that Windows 8 will acquaint a tile-based interface alleged "Mosh" to serve as an another UI for tablets and added low-power touchscreen devices.
We've additionally heard rumblings about a fresh appliance development framework code-named "Jupiter," whose ambition is to advice developers actualize dynamic, visually appealing, and immersive applications for a accessible Windows app store. It may additionally be an attack by Microsoft to accredit developers to actualize apps that assignment on both acceptable x86-based CPUs and ARM-based processors after all-encompassing recompiling and reprogramming.
Speculation
If you agnosticism whether Windows 8 will be a greatly altered operating arrangement from its predecessors, accede this asthmatic bit of advertising that briefly appeared on a Microsoft developer's blog in 2009:
"The minimum that association can booty for accepted is that the abutting adaptation will be article absolutely altered from what association usually apprehend of Windows...The capacity that accept been floated absolutely reflect what bodies accept been attractive [for] for years and it will change the way bodies anticipate about PCs and the way they use them. It is the approaching of PCs."
Microsoft bound removed the blog, as if to abolish the evidence. So is the aggregation absolutely aggravating to agitate things up with Windows 8?
The Big Picture
Microsoft acutely wants to actualize an operating arrangement that scales amid devices. ARM abutment provides the foundation, and billow casework could be a above architecture block. The claiming for Microsoft will be to leave the amount Windows acquaintance and bequest affinity complete while additionally advancing its aerial ambitions.
A final rumor: Reportedly, Microsoft is targeting a 2012 absolution for Windows 8. Anticipate the aggregation can get aggregate ample out by then?
